Reviews Godot physics implementation for known pitfalls. An agent skill from RandallLiuXin/GodotMaker.

  • Works in 5 steps: Read gotchas.md → Scan the implemented code against each… → For each hit → …
  • AFTER implementation
  • SKILL.md covers When to trigger and Review process
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Physics Review is an agent skill from RandallLiuXin/GodotMaker. Reviews Godot physics implementation for known pitfalls. Triggers AFTER implementation, when code involves CollisionObject2D, RigidBody2D, CharacterBody2D, Area2D, collision layers, or physics callbacks. Do NOT use this skill for planning or teaching — only for post-implementation review.

Its SKILL.md is about 300 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `checklist.md` and `gotchas.md`).

It sits in Game Development, covering Game development. It works with Godot. The repository describes itself as: Autonomous text-to-game pipeline for Godot, powered by Claude Code,Codex,Opencode.

When your agent uses it

  • AFTER implementation
  • Code involves CollisionObject2D
  • CharacterBody2D
  • Collision layers

Example prompts

  • “Use the physics-review skill to review Godot physics implementation for known pitfalls. An agent skill from RandallLiuXin/GodotMaker”
  • “/physics-review”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read gotchas.md
  2. Scan the implemented code against each gotcha
  3. For each hit
  4. If no hits, report clean
  5. Optionally run checklist.md static checks for automated verification

What it can do on your machine

Read from SKILL.md and the folder at commit 1d4702c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Physics Review loads about 300 tokens when it runs. Until then it costs about 76 tokens; SKILL.md has 109 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~76
When it runs · the whole SKILL.md, loaded when a task matches
~300

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 109 words (~300 tokens).

“Post-implementation reviewer for Godot physics code. Checks against known gotchas that LLMs consistently get wrong.”

Can I use Physics Review in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add RandallLiuXin/GodotMaker --skill physics-review -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/physics-review, .gemini/skills/physics-review, .github/skills/physics-review and .opencode/skills/physics-review in your project.

What does Physics Review need to run?

SKILL.md names no scripts, command-line tools or credentials: Physics Review is instructions for the agent only.

Does Physics Review access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Physics Review safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Physics Review use?

Physics Review has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Physics Review use?

About 300 tokens (SKILL.md is roughly 1.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
